Abstract

A microcomputer-controlled electronic balance, especially shop or industrial balance, has a keyboard comprising a plurality of individual keys. The individual keys of the keyboard have different stroke heights. The individual keys within the keyboard can be combined in particular regions to form keyboard segments. The stroke heights of the individual keys can be set differently either individually or in particular regions or as a whole. <IMAGE>

Beim Betätigen der Tasten 10, 11, vorzugsweise der Tasten 10 mit dem Finger wird in an sich bekannter Weise jeweils mittels eines nicht dargestellten Tastenstößels auf einer in der Waage eingebauten, ebenfalls nicht dargestellten Leiterplatte eine elektrisch leitende Verbindung zwischen Leiterbahnen hergestellt. When pressing the buttons 10, 11, preferably of the keys 10 with the fingers is produced in known manner in each case by means of a not shown plunger keys on a built into the balance, also not shown, printed circuit board an electrically conductive connection between conductor tracks.

Die gesamte Tastatur 7 ist an ihrer Oberseite durch eine Abdeckmatte 12 und an ihrer Unterseite durch ein nicht dargestelltes Gehäuse abgeschlossen. The entire keyboard 7 is closed at its top by a cover sheet 12 and at its lower side by an unillustrated housing.

Die Einstellung der unterschiedlichen Hubhöhen der Hubtasten 8 kann zB mit Hilfe von (nicht dargestellten) in verschiedener Höhe gestuft angebrachten Vorsprüngen an den vier Seiten eines meist mit rechteckigem Querschnitt ausgebildeten Taststößels und mit Hilfe von damit zusammenwirkenden, entsprechenden Anschlägen in der Stößelführung erfolgen, wobei die Hubhöhe jeweils dadurch eingestellt werden kann, daß der Taststößel je nach dem gewünschten Wert der Hubhöhe um zB jeweils 90° um die Stößellängsachse verdreht in die Stößelführung eingeführt bzw. in dieser umgesetzt wird. The setting of the different heights of the conventional keys 8 can take place eg upgraded with the aid of (not shown) at different heights attached to projections on the four sides of a usually formed with a rectangular cross section Taststößels and by means of cooperating, corresponding abutments in the tappet guide in which the lifting height can be adjusted by in each case that the Taststößel is introduced according to the desired value of the lifting height by, for example, every 90 ° around the push longitudinal axis in the tappet guide or implemented therein.

Control panel or operator input field, especially for control of electronic equipment by input of complex and menu-driven commands has a multiplicity of push button elements whose function, size, shape and position can be varied
